不同地面结构的育肥猪舍NH3排放系数（NH3 Emission Factors of Fattening Pig Buildings with Different Floor Systems）
育肥猪舍 氨气 排放系数
2010/1/28
NH3排放系数是对规模化养殖场NH3排放量估算、NH3减排方法与技术应用效果评估的有效方法之一。通过在模拟实际生产动物人工气候室对3种不同地面结构的育肥猪舍NH3排放相关数据的连续在线检测，研究了不同地面类型猪舍内NH3排放与主要影响因子的相关性及其排放系数。研究得出半缝隙地面猪舍、实心地面猪舍、生物发酵床猪舍内NH3排放系数分别为：(9.47±7.09)、(11.23±4.23)、(4.27±2...
